Hi I tried asking this question yesterday but still had some confusion.Since the area must be in cm^2.
IP The weight of your 1440 kg car is supported equally by its four tires, each inflated to a gauge pressure of 30.0 lb/in^2 .
What is the area of contact each tire makes with the road?
What gauge pressure is required to give an area of contact of 122 for each tire?

Let me critique your work.
OK i have one attempt left, first i change the gauge pressue to newton/m^2? And since P= F/A solve for A after making f = 1440*g? Theni have to divide it by 4 for every tire? but im having trouble with conversions, and my final answer being in cm^2. SOOO confused
